Screening of Legionella pneumophila from water sources in the hospitals in Jakarta

Latar belakang: Pneumonia akibat bakteri Legionella masih menjadi masalah di berbagai tempat di dunia; menjadi penyebab 2-15 % dari pneumonia yang perlu di rawat di Rumah Sakit. Kasus legionellosis di Indonesia dilaporkan terjadi di Bali pada tahun 1996 dan di Tangerang tahun 1999. Keberadaan Legionella di fasilitas Pelayanan Kesehatan berpotensi sebagai penyebab infeksi nosokomial. Bakteri Legionella hidup di lingkungan perairan hangat dan lembab, juga ditemukan diberbagai sumber air seperti, sumber air sistem pendingin ruangan, kolam renang, tempat penampungan air di rumah sakit, perkantoran, hotel, dan perumahan sehingga turut berkontribusi dalam terjadinya community acquired dan pneumonia nosokomial. Metode: Penelitian ini merupakan penelitian deskriptif yang bertujuan untuk penapisan keberadaan Legionella pneumophila diberbagai sumber dan penampungan air di Rumah Sakit (RS) di Jakarta dengan menggunakan medium Legionella Charcoal Yeast Extract (CYE) dan dengan berbagai suplemen. Tujuh belas sampel air yang berasal dari berbagai sumber air di dua RS yang berlokasi diJakarta Utara dan Barat telah diteliti. Hasil: Dua puluh satu koloni yang ditemukan memiliki karakterisitik L. pneumophila dari semua varian medium, namun pada tes agglutinasi latex tidak memberikan reaksi positif. Kesimpulan: L. pneumophila tidak ditemukan diberbagai sumber air dari dua RS ini. Penggunaan metode yang lebih sensitif dan spesifik perlu dilakukan untuk memastikan ditemukannya L. pneumophila.  Kata kunci: Legionellosis, Legionella pneumophila, medium BCYE   Abstract Background: Pneumonia due to Legionella bacteria is still a problem in various places in the world, causes 2 15% of pneumonia that need hospitalization. In Indonesia, legionellosis cases have been reported in Bali in 1996 and Tangerang in 1999. The existence of Legionella in healthcare facilities is potential to cause nosocomial infections. Legionella bacteria live in warm and humid waters, and are also commonly found in various water sources, such as water cooling systems, swimming pools, water reservoirs in hospitals, offices, hotels and housing. These bacteria contribute to the occurrence of community-acquired and nosocomial pneumonia. Methods: This study was a descriptive research, and aimed to screen water sources and reservoirs in the hospitals in Jakarta for the existence of Legionella pneumophilla using Legionella Charcoal Yeast Extract (CYE) medium with various supplements. A total of 17 water samples from 2 hospitals located in West and North Jakarta have been examined. Results: The results showed a total of 21 colonies with characteristics as of L. pneumophila were obtained from those water samples, however, none showed positive results in the latex agglutination test. Conclusion: L. pneumophila was not found thus far in the water sources in these two hospitals. A more sensitive and specific approaches might be used to enable the findings of L. pneumophila.  Keywords: Legionellosis, Legionella pneumophila, BCYE mediu

Outcomes and prognostic factors in parotid gland malignancies: A 10-year single center experience.

Objectives:To describe a 10-year single center experience with parotid gland malignancies and to determine factors affecting outcomes. Study Design:Retrospective review. Methods:The institutional cancer registry was used to identify patients treated surgically for malignancies of the parotid gland between January 2005 and December 2014. Clinical and pathologic data were collected retrospectively from patient charts and analyzed for their association with overall survival (OS) and disease-free survival (DFS). Results:Two hundred patients were identified. Mean age at surgery was 57.8 years, and mean follow-up time was 52 months. One hundred two patients underwent total parotidectomy, while 77 underwent superficial parotidectomy, and 21 underwent deep lobe resection. Seventy patients (35%) required facial nerve (FN) sacrifice. Acinic cell carcinoma was the most common histologic type (22%), followed by mucoepidermoid carcinoma (21.5%) and adenoid cystic carcinoma (12.5%). Twenty-nine patients (14.5%) experienced recurrences, with mean time to recurrence of 23.6 months (range: 1-82 months). Five- and 10-year OS were 81% and 73%, respectively. Five- and 10-year DFS were 80% and 73%, respectively. In univariate analyses, age > 60, histologic type, positive margins, high grade, T-stage, node positivity, perineural invasion, and FN involvement were predictors of OS and DFS. In the multivariate analysis, histology, positive margins, node positivity, and FN involvement were independent predictors of OS and DFS. Conclusions:Our single-center experience of 200 patients suggests that histology, positive margins, node positivity, and FN involvement are independently associated with outcomes in parotid malignancies.

Malocclusion complexity and orthodontic treatment need in children with autism spectrum disorder.

OBJECTIVES This study aimed to investigate the malocclusion complexity and orthodontic treatment need among children with and without autism spectrum disorder (ASD) referred for orthodontic treatment by quantifying the Discrepancy Index (DI) and Index of Orthodontic Treatment Need (IOTN). MATERIALS AND METHODS Dental records of 48 ASD and 49 non-ASD consecutive patients aged between 9 and 18 years (median age 13.0 years) referred for orthodontic treatment were reviewed and compared. The Discrepancy Index (DI) was quantified to determine the malocclusion complexity, and the Index of Orthodontic Treatment Need (IOTN), including the Dental Health Component (IOTN-DHC) and Aesthetic Component (IOTN-AC), was quantified to determine the orthodontic treatment need. Statistical analysis included descriptive analysis, Pearson chi-square tests, Fisher's exact test, Mann-Whitney U tests, and several univariate and multivariate regression analyses. The statistical analysis used descriptive analysis, Pearson chi-square test, Fisher's exact test, and multivariate logistic regression. RESULTS The results show that both malocclusion complexity (DI, p = 0.0010) and orthodontic treatment need (IOTN-DHC, p = 0.0025; IOTN-AC p = 0.0009) were significantly higher in children with ASD. Furthermore, children with ASD had a higher prevalence of increased overjet (p = .0016) and overbite (p = .031). CONCLUSIONS Malocclusion complexity and orthodontic treatment need are statistically significantly higher among children with ASD than children without ASD, independent of age and sex. CLINICAL RELEVANCE Children with autism may benefit from visits to a dental specialist (orthodontist) to prevent, to some extent, developing malocclusions from an early age

Personal and Ambient Air Pollution is Associated with Increased Exhaled Nitric Oxide in Children with Asthma

BACKGROUND: Research has shown associations between pediatric asthma outcomes and airborne particulate matter (PM). The importance of particle components remains to be determined. METHODS: We followed a panel of 45 schoolchildren with persistent asthma living in Southern California. Subjects were monitored over 10 days with offline fractional exhaled nitric oxide (Fe(NO)), a biomarker of airway inflammation. Personal active sampler exposures included continuous particulate matter < 2.5 μm in aerodynamic diameter (PM(2.5)), 24-hr PM(2.5) elemental and organic carbon (EC, OC), and 24-hr nitrogen dioxide. Ambient exposures included PM(2.5), PM(2.5) EC and OC, and NO(2). Data were analyzed with mixed models controlling for personal temperature, humidity and 10-day period. RESULTS: The strongest positive associations were between Fe(NO) and 2-day average pollutant concentrations. Per interquartile range pollutant increase, these were: for 24 μg/m(3) personal PM(2.5), 1.1 ppb Fe(NO) [95% confidence interval (CI), 0.1–1.9]; for 0.6 μg/m(3) personal EC, 0.7 ppb Fe(NO) (95% CI, 0.3–1.1); for 17 ppb personal NO(2), 1.6 ppb Fe(NO) (95% CI, 0.4–2.8). Larger associations were found for ambient EC and smaller associations for ambient NO(2). Ambient PM(2.5) and personal and ambient OC were significant only in subjects taking inhaled corticosteroids (ICS) alone. Subjects taking both ICS and antileukotrienes showed no significant associations. Distributed lag models showed personal PM(2.5) in the preceding 5 hr was associated with Fe(NO). In two-pollutant models, the most robust associations were for personal and ambient EC and NO(2), and for personal but not ambient PM(2.5). CONCLUSION: PM associations with airway inflammation in asthmatics may be missed using ambient particle mass, which may not sufficiently represent causal pollutant components from fossil fuel combustion

Parameter estimation of the kinetic α-Pinene isomerization model using the MCSfilter algorithm

This paper aims to illustrate the application of a derivative-free multistart algorithm with coordinate search filter, designated as the MCSFilter algorithm. The problem used in this study is the parameter estimation problem of the kinetic α -pinene isomerization model. This is a well known nonlinear optimization problem (NLP) that has been investigated as a case study for performance testing of most derivative based methods proposed in the literature. Since the MCSFilter algorithm features a stochastic component, it was run ten times to solve the NLP problem. The optimization problem was successfully solved in all the runs and the optimal solution demonstrates that the MCSFilter provides a good quality solution.(undefined)info:eu-repo/semantics/publishedVersio

Three-dimensional dento-skeletal effects of mandibular midline distraction and surgically assisted rapid maxillary expansion:A retrospective study

It was the aim of the study to provide a three-dimensional evaluation of dento-skeletal effects following bone-borne vs tooth-borne mandibular midline distraction (MMD) and tooth-borne surgically assisted rapid maxillary expansion (SARME). A retrospective observational study was conducted. Cone beam computed tomography (CBCT) records were taken pre-operatively (T1), immediately post-distraction (T2) and 1 year post-operatively (T3). All included 30 patients had undergone MMD (20 bone-borne MMD; 10 tooth-borne MMD). A total of 20 bone-borne MMD and 8 tooth-borne MMD patients had simultaneously undergone tooth-borne SARME. At T1 vs T3, canine (p = 0.007; 26.0 ± 2.09 vs 29.2 ± 2.02) and first premolar (p = 0.005; 33.8 ± 2.70 vs 37.0 ± 2.43) showed significant expansion on the tip level for tooth-borne MMD. This was no significant on the apex level, indicating tipping. Bone-borne MMD showed a parallel distraction gap, whereas tooth-borne MMD showed a V-shape. There was a significant (p = 0.017; 138 ± 17.8 vs 141 ± 18.2) inter-condylar axes increase for bone-borne MMD. In conclusion, bone-borne vs tooth-borne MMD and tooth-borne SARME showed stable dento-skeletal effects at 1 year post-operatively. Bone-borne and tooth-borne MMD seemed not to be superior to each other. The choice of distractor type therefore depends more on anatomical and comfort factors.</p
